  • Patent number: 10720303
    Abstract: An object of the invention relates to the fact that the alignment of the sample stage and the optical image can be adjusted with high accuracy, good operability, and high throughput by utilizing a low magnification optical image and a high magnification optical image. The invention relates to the fact that an alignment adjustment by a sample table alignment can be performed using a first processed optical image obtained by enlarging or reducing or changing a visual field of the optical image of the sample table holding the sample by digital processing, and that an alignment adjustment by an alignment point designation can be performed using a second processed optical image different from the first processed optical image. According to the invention, it is possible to adjust the alignment of the sample stage and the optical image with reference to the outer shape of the sample table and the feature points on the sample without taking out the sample table holding the sample from the sample chamber.

  • Patent number: 10312053
    Abstract: The present invention shortens the time spent in a search for a visual field by a user in a charged particle beam apparatus in which an observation range on a sample is set by using a captured image of the sample. When the contour of a sample table is circularly configured, for example, the central position of a sample table image on an optical image is quickly, easily, and accurately obtained by calculating, from the coordinates of the respective vertices of a triangle circumscribed about the contour created on the optical image by the user, the incenter of the triangle without direct recognition by automatic image analysis, which is complex and time-consuming, of the contour of the sample table image on the optical image.
